Awareness of and Interest in Pre-Exposure Prophylaxis among Patients Receiving Services at Public Sexually Transmitted Disease Clinics in an Urban Setting.

The goal of this study was to assess awareness of, interest in, and sources of knowledge about pre-exposure prophylaxis (PrEP) among 1,464 HIV-uninfected patients from public STD clinics in Baltimore. Logistic regression analyses were conducted to examine factors associated with PrEP awareness and interest. Results suggest PrEP awareness and interest in knowing more about PrEP was highest among men who reported sex with men or with both men and women. White patients were more likely to be aware of PrEP than African American patients, and those reporting consistent condom use were more likely to have heard about PrEP than those who never used condoms. The major source of knowledge about PrEP was health care providers. Findings can inform future prioritization of locally targeted PrEP programs to enhance access to and uptake of PrEP among those most at risk for HIV transmission.
